DEVICE FOR SECURING AND SJJ'LPPORfllINGi"DOOJRIS.

Application fiIed December 28, 1920.

To all whom it may concern:

Be it known that I, HENRY MILLER, a citizen of the United States, and resident of borough of Bronx, in the county of Bronx and State of New York, have invented certain new and useful Improvements in Devices for Securing and Supporting Doors, of which the following is a specification.

My invention relates to improvements in devices for securing and supporting doors, and the object of my invention is to provide a device by which a door or the like may be secured in its open or closed position as well as at intermediate positions. A further object of my invention is to provide a device whereby a door may be supported to relieve the strain on the door, and a further object of my invention is to provide a simple and convenient door lock and supporting device.

I accomplish these objects by the device illustrated in the accompanying drawings in which Figure 1 is a view of the device attached to a door and Figure 2 is an end view of a detail of the lock and Figure 3 is a section on the line 3-3 in Figure 1 and Figure 4 is a view showing a detail of the door, bolt and socket with the several positions shown in dotted lines.

Similar reference characters refer to similar parts throughout the several views.

In a swinging door or gate there is a severe strain on the door and hinges when open or partially open, and in caseswhere no rest is provided on the sill, this strain is constant. This results in unsatisfactory operation of the door, and causes the door to sag which interferes with its operation. A further objection to the doors at present in use is that when not locked in an open or closed position, the door is free to swing frequently resulting in damage to the door and to persons and vehicles using the doorway. y means of my device these objections are entirely eliminated.

I provide upon a door 1 preferably near its outer edge a box 2, which may for convenience be provided with a cover 3 secured to the box my means of screws 4: 4 bolts or the like. Within the box 2 I provide a central pivot 5 upon which I mount a lever 6 by means of a bolt 7 or the like. In the side of the box 2 I provide an open Specification of Letters Patent.

the combination of a Patented June 6, 1922. Serial No. 433,578. I

slot 8, provided with on the under side of the lever 6 I providea lug 10 adapted to engage the teeth 9. This lug 10 is preferably formed by bending over a section of the marginal edge of the lever 6. The end 6 projects beyond the box 2 to form a handle. 011 the lever 6 intermediate the the rack 9, I provide a vertical sliding shaft 12 which is preferably secured to the lever 6 by means of a yoke 12 and a pin 13. At a point on the lever 6 adjacent its inner end, I provide a vertical shaft 14: which may be secured to the lever 6 by means of a yoke 14; and a pin 15. The shafts l2 and 14 are preferably provided with screw threaded end sections or the like whereby they may be extended to any desired length, so that in their normal positions they will not extend beyond the bottom and top respectively of the door 1. Suitable collars 12 and 12 are provided on the extended shaft 12 to bind it in sliding relation to the door, and in like manner suitable collars 14 and 14 are provided on the extended shaft 14 to bind it in sliding relation to the door.

My device being thus assembled and the shafts 12 and 14; lying within the limits of the door, the door may be swung freely on its hinges. When it is desired to lock and support the door the lever 6 is depressed by means of the handle 11 which will drive the shaft 12 down upon the floor and serve as a support for the door which may thus be supported in any desired position. If desired, suitable sockets 16 may be provided in the floor to receive the end of the shaft 12, at one or more positions of the door but it is desirable that these sockets be of such depth as to permit the shaft 12 to raise the door and support it when seated in the socket. The door having been thus sup ported the lug 10 on the lever .6 is caused to engage one of the teeth of the rack 9 thereby serving to finally lock the lever 6 in the desired position. The shaft 14 serves as a counter-balance weight to raise the shaft 12 and it may also be used to engage a suitable socket 17 in the lintel of the doorwziy to lock the door.

aving thus described my invention what I claim is:

1. In a device of the character described lever adapted to be pivoted upon a door, a toothed rack adapta toothed rack 9 and section 11 of thelever ed to engage the lever and a shaft secured to the lever intermediate the rack and the point at which the leveris pivoted substan tially as shown and described.

2. In a device of the character described the combination of a plate adapted to be secured to a door, a lever pivoted thereon, a

toothed rack on the plate adapted to engage the lever a shaft on the lever inter mediate the pivot and therack, and adapted to be depressed by the lever to support the door and a counter-balance Weight on the end section of the lever substantially as shown and described.

3. In a device of the character described New York and State of New York, this ZOthday of December, A. D. 1920.
